JOHN J. DOIDGE, OF SOUTH FRAMINGI-IAM, MASSACHUSETTS, ASSIGNOR, BY MESNEASSIGNMENTS, TO THE R. H. LONG MACHINERY COMPANY, OF SOUTH FRAMING- HAM,MASSACHUSETTS, A CORPORATION OF CONNECTICUT.

GANG EYELETING-MACI-IINE.

Toall whom it may concern:

Be it known that 1, JOHN J. Domes, a subject of the King of GreatBritain, residing at South Framingham, in the county of Mid dlesex andState of Massachusetts, have invented anew and useful Gang Eyeleting-Machine, of which the following is a specification.

My invention relates to improvements in machines adapted to set aplurality of eyelet-s at each cycle of operation, and consists ofcertain peculiar adjusting or positioning means for one or more of themovable sets in such a machine, as hereinafter set forth in detail; andthe object of my invention is to afford practicable, efficient andconvenient means for cutting out and rendering inoperative such movableset or sets as are not needed in any case demanding less than the totalnumber of eyelets which the machine is capable of setting at oneoperation. I attain this object by the means illustrated in theaccompanying drawings, in which- Figure 1 is a front elevation of aportion of an eyeleting machine having my invention embodied therewith,the front plate being omitted and the extreme left-hand lower or movableset being down in inoperative position; Fig. 2, a vertical section takenon lines 22, looking toward the left, in Fig. 1, and, Fig. 3, anenlarged side elevation of one of the movable set drops.

Similar figures refer to similar parts throughout the several views.

Before proceeding with the detailed description of my invention asillustrated in connection herewith, I wish to state that the sets are inthe main similar both in construction and operation to sets commonlyused in machines of the type now being considered, and that they punchthe holes in the stock before setting the eyelets therein, so that theyare in reality combined punches and sets although herein termed setsmerely.

So much of the frame of the machine as is herein shown comprises sidepieces 1 and 3, a cross piece 4 which extends between said side pieces,and a lug 5 which projects from the inside of the side piece 1. Avertical plate 6 is attached to the front ends of the side pieces 1 and3 to cover the opening therebetween. A horizontal work table 7 isfastened by bolts 8-8 to the upper edges of the side pieces or sides 1and-3 in front.

Specification of Letters Patent.

Serial No. 506,751.

So much of the operating mechanism of said machlne as 1s herem showncomprises a vert1oally-movable slide 9 arranged behind the plate 6 to bereciprocated in grooves in the' sides 1 and 8, a portion of a maindriving shaft 10 with its front terminal journaled in the cross piece 4,such shaft having an enlargement 11 at its front. end, a connectingrod12 having its upper end pivoted at 13 to said enlargement eccentricallyto the axis of said shaft, and having its lower end pivoted at 14. tosaid slide, a gang raceway 15 (which cooperates with the movable setspresently to be described) and a bed-plate 16 mounted on ahorizontally-reciprocating carriage 17 for said raceway, only theforward portions of the last three members being represented, and aportion of one of two supporting rods 18 for said carriage, such portionbeing mounted in the lug 5 and carrying thereon a sliding lug 19 whichdepends from and forms a part of said carriage.

In the present case there are seven lower sets arranged in line side byside with spaces 1 between, the two end sets which can be out out ofactive operation being given the reference number 20, and the fiveintermediate sets which are at all times in operative position beinggiven the reference number 21. These sets coact wit-h a correspondingnumber of fixed sets 22 above, in the usual manner. There may be more orless than seven sets in each of the two gangs or series, but there must,of course, be the same number in one series that there is in the otherseries. Moreover, there may be more or less than two drop sets 20 andthe arrangement of the same relative to the sets 21 may vary withoutaffecting my invention in any essential particular. The sets 21arereceived in vertical openings in a block 23 and rest with their bases ona plate 24, the latter being mounted on the slide 9 and said block beingmounted on said plate. Set-screws 25, tapped into the front side of theblock 23, hold the sets 21 against upward displacement. Each set 20 isreceived in a vertical opening in the block 23 and an'alining opening inthe plate 24, and has a flange 26 at the bottom to prevent it from beingwithdrawn from these members inan upward direction. and each set 20 issupported by a drop 27, either in or out of operative position accordingto the arrangement of said drop.

ever number of eyelets it is desired to setm each row, some shoesrequiring more and some less.

.Each of the two drops 27, by means of 'which the location of each ofthe sets 20 is changed in the present case, consists of a cylindricalbody having its rear terminal portion mounted or journaled in ahorizontal opening 28 in the slide 9 near the top, as best shown in Fig.2, such terminal being recessed at 29. The recess 29 is large enough toreceive into it the flanged base of the set 20 above. A lock plate 30,secured by a screw 31 to the face of the slide 9 adjacent to each drop27 and engaging a grooved part 32 of such drop, holds the latter againstendwise movement without preventing the same from being turned in saidslide. In'each side of the drop is a horizontal groove 33. A spring 34has the lower terminal secured to one end of a supporting member 35 onthe face of the slide 9, while the upper terminal of said spring isadapted to enter one of the grooves 33 in the adjacent drop and sonormally prevent said drop from rotating. There isa spring 34 for eachdrop. The two grooves 33 in each drop are on a plane which is atright-angles to the centralplane of the recess 29 which coincides bothwith the axis of said drop and with that ofwhat may be termed the cam(36) of said drop, therefore, the associated spring 34 either retainsthe drop so that its cam is in the highest position or retains the dropso that its cam is in the lowest position, according to which of suchgrooves or of such grooved parts is engaged by the spring, but saidspring does not exert force enough to interfere seriously with theoperator when he desires to turn. the drop so as to carry said cam fromone extreme position to the other. At the front end of each drop is ahandle 37 to facilitate turning said drop. The slide 9 immediately abovethe cams 36 and the recesses 29 is pierced to allow the sets 20 to reston said cams at all times, as is plainly shown in the second vie-w.

From the foregoing it will be clear that, by grasping the handle 37 ofeither drop 27 and turning the latter half way around, thus carrying thegroove 33 engaged by the associated spring 34 out of such engagement andbringing the other groove into engagement with said spring, the cam 36of such drop will be raised or lowered accordingly, said cam going up ifdown and going down if up, and the set 20 bearing on said cam will beelevated or will follow the cam down as the case may be.

The upper sets 22 are secured above the sets 20 and 21 in a series ofvertical passages in a block 38, by means of a series of setscrews 39tapped into the front of said block. The block 38 is on the front of thehood of the frame and is bolted thereto at 40-40.

The raceway 15 is provided with ordinary inverted T-shaped channels 41,there being the same number of such channels as there are sets in eachseries. At their lower terminals the floor of the channels 41 arerecessed at 42 to permit the movable sets to pass through and enter thelowermost eyelets in said channels, it being understood that the latterare so positioned as to intersect at their front ends the paths oftravel of said sets. Yielding stops 43 are provided at the mouths of thechannels 41, the rear terminals of such stops being attached to a'cross-piece 44 that is fastened on top of the raceway a short distancefrom the front end thereof, and the forward terminals of such stopsbeing bent over or around in front of such mouths. The oifice of thesestops is to prevent normally the eyelets from escaping from the raceway,and to yield when the movable sets have picked the lowermost eyelets andsaid raceway is. retracted.

The carriage 17 for the raceway 15 and the slide 9 for the lower setsare timed to each others movements and operate in the usual manner.Holes for the passage of the movable sets are formed in the table 7 onesuch 'holeappearing at 45 in Fig. 2. An adj ustable-work guide or gageis represented at 46.

In practice, after seeing that the drops 27 are properlyadjusted,thestock is placed in exactly the right position on the table7, with the edge of said stock against the gage 4.6, and the sets 20 and21 are caused to rise, the raceway 15 being at the same time retracted,and to punch the holes and set the eyelets taken by the active movablesets (six by the present arrangement) in said stock. This action orthese actions are or may be repeated indefinitely, and whenever adifierent number of eyelets is required for the work one or both of thedrops 27 are adjusted or readjusted as may be necessary beforeproceeding with the setting operation.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in an eyeleting machine, with a set, and a suitablereciprocating supporting member therefor, of' a rocking member mountedin such supporting member beneath and in supportingrelation to said setand adapted to retain said set in either an operative or inoperativeposition according to the adjustment of said rocking member, the latterbeing held in operative position against endvvise movement.

2. The combination, in an eyeleting machine, With a reciprocatingmember, of a rotatable drop mounted in such member and provided with acam, means to hold said drop against endwise movement, means to retainsaid drop in either of two normal positions, and a set in saidreciprocating member resting on the drop cam.

3. The combination, in an eyeleting machine, with a reciprocatingmember, of a circumferentially and longitudinallygrooved rotatable dropmounted in such member and provided With a cam, engaging means for thecircumferentially-grooved part of said drop to hold the latter againstendvvise movement, resilient engaging means for thelongitudinally-grooved parts of said drop to retain the latter in eitherof two normal positions, and a set in said reciprocating member restingon the drop cam.

41. In an eyeleting machine, a drop for a set, such drop consisting of arocking member provided With a set-supporting cam.
